The scatterplot shows data set A, which consists of the weights y , in pounds , of a Labrador retriever puppy at various ages , x , in months. The equation of a line of best fit for the relationship in data set A can be written as y = -5.1 + 8.7x , where 2 ≤ x ≤6 .

The puppy was weighed again at 9 months old and weighed 52 pounds. Data set B consists of all the data points in data set A as well as the data point (9, 52). The equation of a line of best fit for data set B can be written as y = r + sx, where rand s are constants and 2 ≤ x ≤ 9 . Assuming the equations of the lines of best fit are calculated in the same way, which of the following is the best estimate for the value of s?
